SPECIFICATION forming part of Letters Patent No. 38%,312, dated June 12, 1888.

Application filed March 16, IBSS. Serial No. 207.304. (No nioilclJ To (1213 whom it may concern.-

Be it known that l, FRANK AVERILL Fox, of New York city, New York, have invented anew and Improved Oar-Conpler, of which the following is a specification.

This invention relates to various improve ments upon Letters PatentNo. 367,613 granted to me August 2, 188.

The invention has for its object to increase the ell'cct-iveness of the coupler and to improve the working of its different parts. The invention consists in the various features of improvement more fully pointed out in the claims.

In the accompanying drawings, Figure 1 is a top view of myimproved cannonpler. Fig. 2 is a side view of the draw-bar; Fig. 3, aside view of the draw-head; Fig. 4, a side view of the bolt, and Fig. 5 an end view of the operating-lever.

The draw-bar A is composed of a top and bottom bar, a a, connected by cross-pieces b b, to which the bars a a are riveted. The cross piece I) is set back from the forward end of bars a, so that the latter constitute a pair of jaws, between which the shank c of draw-head c is pivoted by pin (1. The shank c is slotted or perforated at its edge, and this perforation is engaged by the forward end of a sliding bolt, 0, that is guided by and passes through perforations in the cross-pieces b b. Between these cross-pieces the bolt 6 is surrounded by a coiled spring, f, abutting at its rear end against cross-piece b and at its forward end against a shoulder, e, on bolt 3. Forward of such shoulder the bolt 6 is embraced by the forked end g of the operating-lever g. This lever is pivoted to a peculiar extension of the forward crosspieee, Z). This extension Z) eon stitutes in effect a lug projecting beyond the top and bottom bars a and entirely clearing such bars.

it will be seen that by oscillating the lever 9 it will force the bolt 0 out of engagement with the draw-head and permit the latter to swing on its pivot. As the lever g is released, the spring j will throw the bolt 6 forward to reengage the perforation in the draw-head as soon as the latter is in line with the bolt.

The shank c of the drawdiead c has a lateral 5o hook-shaped extension, 6, which limits the motion of the draw-head when opening by striking against the ing 1). To prevent the draw-head from closing beyond its proper position-that is, from turning too tarinward on its pirat -I have made the rear edge ofshank c of peculiar shape-that is to say, the edge of the shank is curved from hook c to the perforation that is engaged by the bolt, as shown at a", while forward of said perforation the edge is entirely straight, as shown at This straight section 0, as will be readily understood, bears against the forward side of crosspieee b whenit is attempted to turn the draw head inward any farther than until its perforation is in line with bolt 6. Thus the motion of the drawhead inboth directions is limited. At the side opposite to the extension c the shank c has an extension, 0". In the act of coupling, the draw-head of one car, after hav- 7:
